topic: internal config option to fix hg pick behavior (issue6406)

After some consideration, hg pick was made to always use current topic (and
topic namespace), even if it's not set, in which case the resulting changeset
will not have any topic.

Previously the intended behavior was to only update topic if there was an
active topic, and not touch commit extras at all otherwise. That wasn't ideal,
since pick doesn't change active topic, and amending the just-picked commit
would unset its topic without clear user's intent to do so and to their
surprise.

case 1: new changeset (draft with topic namespace)
==================================================

topic namespace of that changeset is reported

  $ hg clone orig case-1 -q
  $ cd orig

  $ echo apple > a
  $ hg ci -qAm apple

case 2: obsmarker affecting known changeset
===========================================

topic namespaces of both the precursor and the successor are affected

  $ hg clone orig case-2 -q
  $ cd orig

  $ echo broccoli > b
  $ hg debug-topic-namespace bruce
  $ hg ci --amend -m 'broccoli'

case 3: phase divergence
========================

3 phase divergence resolution can point to a thing but not affect it (probably not affected)

In this case, the pushed changeset comes with an obsmarker whose predecessors
has the `charlie` topic-namespace and the successors has the `carol`
topic-namespace. However, that obsolescence is part of a phase-divergence
fixup, so we should now mark `coconut` as affected since it is already public.

  $ hg clone orig case-3 -q
  $ cd orig

  $ hg debug-topic-namespace charlie
  $ hg topic c
  $ echo coconut > c
  $ hg ci -qAm 'coconut'

  $ hg debug-topic-namespace carol
  $ echo cloudberry > c
  $ hg ci --amend -m 'cloudberry'

  $ hg phase --hidden -r 'desc("coconut")' --public
  1 new phase-divergent changesets

  $ hg evolve --phase-divergent
  recreate:[s1] cloudberry
  atop:[3] coconut
  committed as 9f1abc6f4a6f
  working directory is now at 9f1abc6f4a6f

case 4: phase movement: publishing drafts

topic namespaces of published changesets are affected

  $ hg clone orig case-4 -q
  $ cd orig

  $ hg push ../case-4 --publish
  pushing to ../case-4

  no changes found

  active topic 'c' is now empty
  (use 'hg topic --clear' to clear it if needed)

case 5: bookmark movement
=========================

Bookmark movement that affect tns (like putting a bookmark on obsolete
changesets) their topic namespaces reappear and are therefore reported

  $ hg clone orig case-5 -q
  $ cd orig

  $ hg debug-topic-namespace dana
  $ hg topic d
  $ echo durian > d

case 6: phase movement: publishing secret changesets
====================================================

(that are known on the server)

topic namespaces of published changesets are affected

  $ hg clone orig case-6 -q
  $ cd orig

XXX: we see "active topic is now empty" twice because stack doesn't handle topic namespaces yet

  $ hg push ../case-6 -r . --publish
  pushing to ../case-6
  searching for changes
  no changes found
  topic namespaces affected: dave
  active topic 'd' is now empty
  active topic 'd' is now empty
  (use 'hg topic --clear' to clear it if needed)
  [1]

previous topic namespace is resurrected...

  $ hg phase --secret --force -r . --config 'devel.tns-report-transactions=phase'
  topic namespaces affected: dave
  active topic 'd' grew its first changeset
  (see 'hg help topics' for more information)

...just to disappear again

  $ hg push ../case-6 -r . --config 'devel.tns-report-transactions=*'
  pushing to ../case-6
  searching for changes
  no changes found
  topic namespaces affected: dave
  active topic 'd' is now empty
  (use 'hg topic --clear' to clear it if needed)
  [1]

  $ cd ..

case 7: phase movement: secret->draft on the server
===================================================

changeset becomes visible to peers, so its topic namespace is affected

  $ hg clone orig case-7 -q
  $ cd orig

  $ hg phase --draft --force -r tip
  active topic 'd' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg phase --secret --force -r tip -R ../case-7
  active topic 'd' grew its first changeset
  (see 'hg help topics' for more information)

  $ hg push ../case-7 -r . --config 'devel.tns-report-transactions=*'
  pushing to ../case-7

  $ cd ..

case: 99 pushing obsmarker for an unknown changeset
===================================================
doesn't affect any topic namespace, we report nothing

  $ hg clone orig case-99 -q
  $ cd orig

  $ hg debugobsolete aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa `getid "desc('dragonfruit')"`
  1 new obsolescence markers

  $ hg push ../case-99
